OBJECTIVE: Evaluate the association between inflammatory process, adiposity, and vitamins A, D, and E in adolescents, according to gender.
METHODS: Cross-sectional study with adolescents aged 12-19 years old of both genders attending public schools in Recife. A questionnaire was used to collect data on socioeconomic level, lifestyle, and food intake of adolescents. Then, an anthropometric evaluation and a blood sampling were performed to analyze serum concentrations of α-1-acid glycoprotein, retinol, β-carotene, α-tocopherol, and 25-hydroxy-vitamin D.
RESULTS: The levels of α-1-acid glycoprotein were higher for abdominal obesity in both genders. Male adolescents with insufficient serum α-tocopherol levels had low levels of α-1-acid glycoprotein (p=0.03) and an increased risk of 25-hydroxy-vitamin D and β-carotene deficiency in relation to total and abdominal fat; female adolescents had an increased risk of insufficient β-carotene with abdominal obesity (PR: 1.33; 95% CI: 1.2-1.5).
CONCLUSION: Abdominal adiposity implies a higher risk of inflammation and causes different changes to the levels of fat-soluble vitamins according to gender.
